PLIER HANDLES 0F SHEET METAL Filed March 19. 1928 INVENTCR EEEE wPatented Apr. 14, 1931 UNITED STATES PATENT OFFICE CHARLES F. BENEDICT,OF NEW YORK, N. Y., ASSIGNOR OF TWO-THIRDS TO K. C. SEEL- BACK COMPANY,OF NEW YORK, N. Y., .A. CORPORATION OF NEW YORK .PLIER HANDLES OF SHEETMETAL Application filed March 19, 1928. Serial No. 262,837.

This invention relates to handles for pliers constructed of sheet metalstampings, and its object is to provide a form of construction in whichwidth and form is given to the 5 handle elements by bending a portion ofeach, under and back; the bending in each case being from the top faceof the implement, and the result being, that an unbroken surface area ispresented on the top face of 10 the implement from the joint to the rearextremity thereof; while the handle portions which are turned underpresent a uniform appearance and extend only from the rear 7 extremityto a point near to the plier joint.

Another object is a means for the stiffening and strengthening of theoint; which means is provided by a form of swedging adjacent to therivet of the said joint.

These and other objects and features of the invention will be fullydescribed in the following specification and claims, and illustrated inthe accompanying drawings, in which: 7

Fig. 1 shows a top face view of a plier in which the handle form isillustrated; the jaws being indicated in dot and dash lines.

Fig. 2 shows a section on the line 22 of Figure 1.

Fig. 3 shows a section through the joint on the line 3-3 of Figure 1.

Fig. 4 shows the bottom, or reverse side of the implement andillustrates the underlapped portions of the handles.

Fig. 5 shows a section on the line 55 of Figure 4.

Fig. 6 shows a top edge view of the upper element only, as illustratedin Figure 1.

The forming of pliers and similar implements of sheet metal is an oldart, but certain novel improvements are presented in this inventionwhich greatly increase the serviceability of the tool as well as add toits symmetry of appearance.

Plier handles have previously been constructed in which turned overportions have been bent from the main body of the handle element; but itis believed that, in all prior cases the elements have been so assembledthat the said overlapped portions were turned in opposite directions toeach other so that looking at the plier from the top side, one of theportions would be turned upward and the other downward with respect tothe said handle elements. Such a form of construction in ununiform andunbalanced and does not present the symmetry of form and appearancewhich is apparent in the handles herewith illustrated.

The strength and appearance of the tool herewith shown, is also enhancedby the swedging of the metal adjacent to the joint rivet.

Referring now to Figure 1 of the draw- 1ngs; the handles shown comprisethe elements 10 and 11 which are joined together by means of the rivet12, or by a screw if desired. The jaws of the plier are indicated by thedot and dash lines 13 and may be of such varied forms as required eitherfor gripping or for cutting purposes. The swedged portion 14; whileshown in ring formation, may be of any suitable geometric design, theobject being to force portions of the metal into forms of contour invariable planes in order to better resist the bending and twistinstrains set up at this point when in use.

eferring now, to Figure 3; it will be seen that an underlapped portion17 is bent over from the main body of the element 10; while a similarportion 18 is bent over from the element 11, the portion 18 beingslightly bent inward as shown.

In the reversed view as illustrated in Figure 4; the underlappedportions 17 and 18 may be clearly seen; they extend from the rearextremity of the plier to a point back of the joint, terminating in thewide flared portions as seen at 19 and 20.

Referring to Figure 6 of the drawings; it will be seen that the topsurface of the element 11 is in a straight horizontal line; while theunder side is bent downward below the line of the joint and the swedgedring 14. This metal is formed over in this manner to give grippingsurface on the handle and to strengthen it by reason of the contouredformation. Now, if the metal in the opposite handle element 10 wereturned over in an upward direction in the manner commonly used prior tothis invention; then the turned jectionable Ifeature ito some extent bybending both flared portions of the handle so that the portions 17 and18, as-seen in Figure 3, are both on one side of the handle. This bringsthe lines of applied force closer together and produces a moreefficient, and a better appearing tool. ilhe turned over'portions ofboth handles terminate in the vwide flaring members 1 9 (and 20 as seenin Fig ure 4. I

Reterr-i-ng now-to the illustration seen in Figure 5; it will be seenthat the flared per- 8 tion 18 is slightly bent inward. This is done toit .into alignment with the portion 157 and gives a more symmetricalappearance. iOtherwiseithasnontility.' v

Ihe form of construction herewith shown and described is, by reason ofthe better alignment of the handles, a more efficieht and practical toolthan is found in sheet metal gpliers .as now ,made, and it alsopossesses greater symmetry and beauty of outline be cause the time endportions 19 and 20 are both on one side, and the top. surface of thetool presents an unbroken a-nd uniform sur-v trace appearance. 7
